Curiously, I ran this with Crafty 15.19 on a PII 300, and it liked Nxh5 until
ply 12 7/32.  Evaluation is around +.57 until then, then it suddenly jumps to
+2.57 at ply 12 3/32. At 3'47", it changes to Rfe8, with a +2.27 evaluation.  It
doesn't even appear to consider Qxa2 at any time in the search.
Could there be a bug here?
